No, not if you're a full-time regular employee. OSS is the sole compensation regular full-time members are entitled to receive for overtime. Members are not entitled to additional compensatory time off, or “CTO”, for any overtime they may have to work.
However, the master agreement does provide, at Clause 13.01, that work schedules are determined by mutual agreement between employees and management. The employer does not have the unilateral right to fix work schedules. An occasional, incidental requirement to work an evening or weekend day is just part of the deal that comes with OSS: members are assured of seven per cent of annual pay as overtime compensation; the employer is assured that employees will deliver whatever incidental overtime may be needed to get the job done.
However, where a member is faced with a regular, ongoing, predictable requirement to work outside the normal work schedule, the PEA's advice to members is that they exercise their rights under Clause 13.01: seek an agreement with local management to modify the work schedule to include the requirement in the regular work schedule.
Article 13 of the master agreement provides that if the employees and local management are not able to agree on a schedule, the matter can be referred to a joint committee for resolution. The committee is chaired by a third-party neutral who has authority to settle unresolved issues and impose a work schedule when the parties are not able to agree among themselves.
Members who occasionally have to work a weekend day to get their job done won't get far asking the joint committee to order a change in their work schedule. However, prospects are better if a professional is required, say, to attend an all-day meeting with a client group on the third Saturday of every month.
The master agreement contains no language entitling the employer to schedule overtime. Where the employer is in a position to predict that given work will be regularly required on a workday evening or a Saturday or a Sunday, and where those times fall outside the employee's regular work schedule, our collective agreement does not entitle the employer to add the required hours to the employee's work schedule, thereby raising the average to more than 35 hours a week. Clause 13.01 is not subject to any proviso that the employer may increase scheduled hours of work in consideration of the 7 per cent OSS compensation.
When faced with regular and predictable work requirements which fall outside normal hours, members can and should argue that such requirements ought to be built into regular work schedules.
