Health
In busy locations, signalling can be very challenging and stressful, in a manner similar to air traffic control. Signallers are therefore susceptible to stress-related illness. Following protracted industrial action from unions and, much more recently, detailed studies on fatigue and ergonomics in the rail industry, prudent operators implemented strict guidelines relating to the length and number of consecutive shifts permissible for safety-critical workers, including signallers. These guidelines are ideally aimed at improving safety and reducing fatigue at work, but also the overall lifestyle of employees. In some cases, physical changes in the work environment also followed these studies, including changes in the design of signal box lighting, seating and signalling equipment.

Famous quotes containing the word health:
“While I am to crawl upon this Planet, I would willingly enjoy the health at least of an insect.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“As they move into sharing parenting, men often are apprentices to women because they are not yet as skilled in child care. Mothers have to be willing to teach fathers—both by stepping in and showing and by stepping back and letting them learn.”
—Nancy Press Hawley. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 6 (1978)
“To thee, fair Freedom! I retire
From flattery, cards, and dice, and din:
Nor art thou found in mansions higher
Than the low cot, or humble inn.
‘Tis here with boundless pow’r I reign;
And ev’ry health which I begin
Converts dull port to bright champagne;
Such Freedom crowns it, at an inn.”
—William Shenstone (1714–1763)
