Your prospective employer indicated to you that working days are Monday to Friday and that there may be exceptions.
You don't want to work Saturdays.
You have two options:
- Tell them explicit do you don't want to work Saturday and you want this to appear in your contract. This will make it clear to them what you want and not want to do.
- Tell them your are not keen on working Saturdays; Accept the offer and wait for the best.
As I see it, in the first case, you risk not getting the offer because sometimes the employer expect people to work Saturdays. In the second case, you will have to work some Saturdays.
This is the tough reality and I don't see how you can convince them to make an exception without saying it out specifically. If you are an exceptional individual they cannot succeed without, they may make an exception.
Young companies are often hectic environment with low staff count. Everybody is expected to pull their weight and take on all kind of responsibilities. Those companies are more fragile and working on Saturdays may be life or death for the company.
You can also ask them how you would be compensated if you are ask to work on Saturdays.
You have to ask yourself if you really want this job or not and what you are willing to sacrifice for it.
If you don't want to work Saturdays, you may want to pursue more established organizations.
