I’m trying to figure out

I’m trying to figure out whether it is worth trying to get to work on Friday and Monday by train whilst the guards are having their stupid, pointless, irrelevant, stuck-in-the-dark-ages strike. According to the announcement I heard on the way home this evening, South Central will be running no services west of Barnham. South West are not involved in the strike and will be running a "very limited" service, but if they run the scheduled 0845 to Brighton, I should be able to get to work just ten minutes late. Guards on Wessex are to be re-balloted, but if they run their normal service, the train that I use to get home will still be running.
But there are rather too many "if" factors in there for my liking.
UPDATE: asked at the station, and it seems that I will be able to travel. by train without too many problems.
