Mr Bell says he's appalled the Unite union is threatening a 12-day strike at the busiest time of the year, when tens of thousands of people rely on public transport.
Unite has said with no resolution in sight it has no option but to take action in the dispute over changes to drivers' contracts.
Mr Bell says a strike during TT has the potential to cause maximum disruption to the economy - but says the Island won't be held to ransom.
The Chief Minister says it's a cynical move:
Meningitis B vaccination scheme to be rolled out on-Island
Programme is for eligible Year 13 students and under-25s
Balthane Roundabout plans on hold until 2027/28 as costs rise
Price tag has jumped up by £600,000 since scheme was first approved
Port St Mary lifeboat launched to rescue stricken fishing vessel
RNLI crew tows vessel back into harbour
Enquiries ongoing after 'shotgun-like sound' heard near Police Headquarters
Police say there's no indication of any wider risk to the public
