As you are no doubt aware, 30 November will see widespread disruption to public services due to strike action being taken by numerous trade unions.
I work in a high-profile government department, but I am not a union member and I do not intend to strike. I have been offered the opportunity to cover at a national airport next Wednesday (can you guess the govt. dept

) so to ensure they don't grind to a halt. Furthermore, in order to provide said cover, I will have to rake in an obscene amount of overtime this weekend in order to prepare me for the role. This overtime will cover Christmas in my household.
Am I making the right choice in crossing the picket line? The reason I'm not striking, aside from not being a union member, is one of selfish rational choice - the government will do whatever they want, and it doesn't matter if Kirkstaller comes into work or not. So, I might as well take them for all I can in overtime.
My office isn't the kind of place where strikebreakers would get shunned or abused, but the current atmosphere is noticeably more hostile than during previous disputes. Also, the pickets at the airport are likely to be a lot more militant than the Trotskyites at my gaff.
Advice would be appreciated, gentlemen.
