Employer introducing on-call without contract clause or compensation, advice needed

Posted by Odd-Drummer3447@reddit | ExperiencedDevs | View on Reddit | 250 comments

I'm a Senior Developer in the Netherlands, starting a new role a couple of months ago. My employer just shared an on-call schedule that includes me for the Christmas holidays (yes, including Dec.25 too).

Situation
- On-call duties were NOT mentioned during hiring or in my employment contract.
- Requirements: 24-hour availability, have laptop/phone ready, be sober enough to respond professionally.
- No compensation or time-off-in-lieu mentioned.

After checking with colleagues, NONE of them have on-call in their contracts either. This appears to be a new policy being introduced for the first time.

Christmas is particularly important to me as I haven't seen my family in a year.

My plan
I'm considering privately messaging my manager to discuss:
- Reduced on-call window (business hours instead of 24 hours)
- Compensation (extra vacation day or pay)
- Formal contract amendment for future on-call expectations

Questions for other devs
1. Am I being unreasonable pushing back on this, or is this a legitimate concern?
2. For those in the Netherlands/EU: what are typical on-call arrangements and compensation?

Three years ago I quit a company because right after I finished the trial period, they told me that every dev was obliged to be on-call one week per month, and no compensation was provided. No one told me that during the hiring process, and it was not included in the contract. Again, in the Netherlands.

I want to be professional and collaborative, but also set healthy boundaries.

Any advice from those who've navigated similar situations?
